Application filed July 25, 1905. Serial No. 271,138.

To all whom, it 71 1/04 concern.-

Be it known that I, PEYTON RoBB, a citizen of the United States,residing at Walcott, in the county of Greene and State of Arkansas, haveinvented new and useful Improvements in Sewing-Machine Attachments, ofwhich the following is a specification.

My invention has relation to new and useful improvements insewing-machine attachments which are used in conjunction with the headof a sewing-machine and quilting-frame.

The object of my invention is the production of a device of this classthat may be conveniently and readily attached to the head of asewing-machine and a quilting-frame and with the assistance of said headand frame stitch a quilt or other covering in an eflicient and expedientmanner.

WVith these ends in view my invention consists in the novelconstruction, combination, and arrangement of parts, as is hereinafterset out in the specification and claims hereuntoattached.

In the accompanying drawings, in which like parts are designated by likecharacters throughout the several views, Figure 1 is'a perspective viewof my invention as applied. Fig. 2 is alongitudinal vertical sectionalView of my invention out on the line X X of Fig. 3, the dotted linesrepresenting a band which passes around the crank and pinion wheels ofmy invention and the band-wheels of the head of a sewing-machine. Fig. 3is a top plan view of my invention. Fig. 4: is a front end View of myinvention.

My invention is described as follows:

The numeral 1 represents trestle or other benches to support myinvention. I

2 represents the frame of my invention, said frame consisting of twoopposite longitudinal beams 3 and cross-beams 1. Secured to saidcross-beams 4 midway between said longitudinal beams 3 is a longitudinalbeam 5, provided with a longitudinal groove in which is secured arack-bar 6. Slidably mounted on said longitudinal beams 3 are twooppositelydisposed beams 7 and 7 secured together by means ofcross-beams 8. The lower ends of said beams 7 and 7 are constructed insuch a manner as to provide outer flat portions and downwardly-extendingflanges 9. When in position, the said beams 7 and 7 are slidably mountedon said longitudinal beams 3 of said frame, so that the outer fiatportions thereof rest on the upper faces of said beams, which beamsconstitute the track, the said downwardly-extending flanges 9 coming incontact with the inner faces of said beams 3, and thereby preventing anylateral movement of said beams 7 and 7. -Secured to and extendingdownwardly from said cross-beams 8 is a beam 10, provided with twoperforations 11 and 11'. Journaled in the said perforation 11 of saidbeam 10 is one end of an axle 12, the opposite end of which axle isjournaled in a perforation in said beam 7 and is rigidly secured to thecentral part of a crank-wheel 13, provided with a crank-handle 13.Bigidly secured to a pinion 1 1, located near the rear portion of saidbeam 7, is an axle 15, said axle being journaled in a perforation insaid beam 7 and the perforation 11 of said beam 10, said axle havingextending eccentrically from its inner end a pivot 16. Pivoted to saidpivot 16 at its upper end and extending downwardly therefrom is apush-lever 17 the extreme lower end of which terminates in achisel-shaped portion 17 which engages the said rack-bar 6 when myinvention is in operation.

The operation of my invention is as follows: Iset the frame of myinvention on said benches 1 and mount the said beams 7 and 7 on saidlongitudinal beams 3, as described. I then place the head 18 of asewing-machine on said cross-beams 8, place one side of a quiltingframe19 under the arm 20 of said head 18 and pass said band 18 around thecrank and pinion Wheels 13 and 14, respectively, of my invention andtheband-wheel 18 of said sewingmachine head 18. I then turn the crank-wheel13 by means of the crank-handle 13, also causing said pinion-wheel andband'wheel to rotate, said pinion-wheel14 by means of the said axle 15and eccentric-pivot 16 causing said push-lever to engage the teeth ofsaid rackbar 6 and propel said beams 7 and 7 along said longitudinalbeams 3 of said frame 1 and carry with them said sewing-machine head,which stitches the quilt or other covering. It will be obvious that theseams may be stitched any desired distance apart by setting thequartergage of the sewing-machine head. After stitching one line I movemy invention toward the quilt or other covering until the quartergagecomes directly over the seam and raise the push-lever 17 and slide thetwo oppositelydisposed beams 7 and 7 back to the opposite end of theframe and proceed as before. When the quilt or other covering isstitched as far as the arm of the machine-head will allow, the quilt isrolled on the near side beams IIO of the quilting-frame, and whendesired the other side of the quilt may be put under the arm of thesewing-machine head.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A sewing-machine attachment, consisting of a frame 2, consisting oftwo opposite longitudinal beams 3 and cross-beams 1; a longitudinal beam5, provided with a longitudinal groove, secured to said cross-beams 1,midway between said longitudinal beams 3; a rack-bar 6, secured in'thesaid longitudinal groove of said longitudinal beam 5; twooppositely-disposed beams 7 and 7, secured together by cross-beams S,said beams provided with two perforations 11 and 11; an axle 12,journaled at its inner end in said perforation 11, of said beam 10, itsopposite end journaled in a perforation in said beam 7 a crank-wheel 13,provided with a crank-handle 13, said wheel being rigidly secured at itscentral part to the last-mentioned end of said axlel2; an axle 15,journaled at its inner end in the perforation 11', of said beam 10, itsopposite end journaled in a perforation in said beam 7; a pinion 14,secured at its central part to the said axle 15; a pivot 16, extendingeccentrically from the inner end of said axle, and a pushlever17,pivoted to said pivot 16 at its upper end, the extreme lower end of saidlever terminatingin a chisel-shaped portion 17, which engages in saidrack-bar 6, substantially as shown and described and for the purposesset forth.
